Press fit bushing, How do I calculate bushing ID after press fit 1

[kurtmcm]

I am trying to calculate how much a steel bushing that is press fit into a steel housing will shrink on the ID so that i can tolerance the shaft that goes through it properly. I have not had any luck finding this calculation.

Thanks,
Kurt

Hi kurtmcm

Follow this link it takes you to the formula that the calculator is based on and if you scroll down to near the bottom it explains the obid and ibod which your looking for.
I have never personally used this calculator.

Hello to all that have helped.

I have been in contact with A. Slocum who did the calcs on the engineersedge website desertfox directed me to.

This web site has a lot of excel calcs you can down load.

The press fit calc is called "joint_press_fit.xls"

I am currently using the Areabefore = Areaafter (sugested by "Thetick") therory to determin the ID after press fit.

Thankyou for your help.
